4(b) shows the experimental cooling curve that corresponds to 'tc1' plotted together with five numerical cooling curves.
They are arranged in sections on heat transfer, modeling and simulation, distortion and residual stresses, property predictions, quenchants and quenching, gas quenching, hardenability, cooling curve analysis methodologies, and dilatometric analysis, modeling quenching and tempering induced phase transformations in steels, predicting quench-hardness within the whole volume of axially symmetric workpieces of any shape, the gas-cooling of multiple short inline disks in flow along their axis, and the dilatometric analysis of aging in aluminum alloys.
A cooling curve, shown in Figure 1, depicting this behavior can be obtained by plotting, on semi logarithmic axes, the fractional unaccomplished temperature difference versus time.
Again, by connecting the dots (according to best fit) and continuing to draw a straight line to where it intersects the x-axis, we have the approximate cooling curve for the Sure Temp.
Comparisons between the cooling curve from the casting against the calculated TTT curve are used to evaluate a part for embrittlement.
Combination of experimental cooling curve and numerical simulation using INC method give the following values of average relative errors between:
Typically a cooling curve of ideal crystalline polymers, excluding rate effects, consists of three stages as shown in Fig.
The acceptable range for the peak temperature is 2,200-2,500F (1,204-1,371C), as shown in the cooling curve in Fig.
Physical interpretation of each thermal parameter from the cooling curve and its first derivative for cast irons has been explained in literature (Ekpoom & Heine, 1981; Labrecque & Gagne, 1998).
Thermal analysis measures the cooling curve of the solidifying alloy.
By comparing the experimental heating and cooling curve with the simulated one, curve C in Fig.
